Abstract

• In the present study, Crotalaria juncea L. belongs to the family Fabaceae which is grown in Kyaing Tong University Campus. In the present study, morphological characters, anatomical characters, physicochemical properties and antimicrobial activity were carried out. In morphological characters, erect, simple or branched, appressed hairy, annual herbs, stem conspicuously striated, leaves oblong to oblanceolate. Flowers terminal racemes, bracts and bracteoles linear, corolla golden yellow; pods cylindrical, brown silky. In anatomical characters, the stomata anisocytic types which abundant on both surfaces and unicellular, uniseriate trichomes abundant on lower surface. Leaves and stem shows non-glandular, unicellular and uniseriate trichomes. In physicochemical properties, the aqueous extracts showed more soluble than other solvents. In antimicrobial activities, results revealed that Crotalaria juncea L. possess significant antimicrobial activities against Aspergillus flavous and Bacillus subtilis.
